well i have two green frogs. ones albino and ones not. they are both less than a year old and im guessing they are a about a month apart in age. anyway the normal frog is a male (he started to sing) and the albino i still dont know what she is although tonight they did this:

as they did this the normal one on the bottom was singing. i dont even think they are sexually mature. are they? what could have stimulated them to do this? ive been changing the hours the light is on so that it matches the daylight outside to make it more natural. could it be that its becoming spring and theres more light in their tank?
